Abstract (en)

The purpose of the invention is to allow the work height of a work device to be easily and appropriately adjusted by a remote operation that uses a remote operation device for a work vehicle during automatic travel. An automatic travel system for work vehicles comprises an automatic travel unit, and a remote operation device (3), for a work vehicle. A work vehicle (1) has a work height setting unit (51, 52), a height detector (55, 56), a raising and lowering indicator (54), and a raising and lowering control unit (44B), for a work device. The raising and lowering control unit (44B) sets a control target height to a work height on the basis of the indication of the raising and lowering indicator (54) and executes automatic raising and lowering control so that the height position of a work device (6) matches the work height. The remote operation device (3) has a display device (4) that displays remote operation information, and a work height adjustor (60C, 60D, 60F, 60G) that allows adjustment of the work height while in automatic travel mode. The display device (4) has a work height display section (60K, 60L) that displays the work height of the work device (6), the work height after adjustment, and the height position of the work device (6).
